This invention relates to improvements in film magazines for motionpicture cameras, the principal object of the invention being to providea magazine comprising twin sections having convenient carrying means andmeans whereb the magazine may be placed on a floor or ot er support inan upright position without damage to a film carried by the magazine.

Another object is to provide a magazine having means for centeringthesame in proper position on a camera.

A further object of the invention is generally to improve theconstruction of the magazine so as to increase the efliciency of thelight locks at all connecting portions of the magazine. i

Other objects and advantages of the invention will appear as thedescription prol ceeds.

In the drawings accompanying this specitcation,

Figure 1 is a partly sectional side eleva-l tion of a magazine embodyingthe features i of the present invention; and

Fi ure 2 is a cross sectional view taken approximately on the line 2--2of Figure 1.

Referring to the drawings, the magazine housing comprises twin sections1 and 2 of ap- 80 proximately circular form, said sections constitutingrespectivel the supply section and the take-up section or a travelinglilm 3. E

The sections are connected in tangential relation to each other, bymeans of webs 4 and are also'united at what may be termed I their upperside by the merging together of their peri heral walls as shown at 5,Figure 1, from w ich merged peripheral portion clends a partition orwall 6 integral with but 4 ying in a plane at right angles to the webs4. The sections 1 and 2 are further connected together b ahandle 7formed integral with the perip eral walls oi? the sections, said ihandle bridging or spanning the s ace between the sections at a pointabove t e partition 6 and forming a convenient means for lifting andcarrying the magazine. Y

At the side of the ma azine opposite from the handle 7, an L-shape onthe peripheral wall of each of vthe secextension is formed A CORPORATIONOF vNEW YORK FILM MAeAzINE Application med september a, i929. serial No.391,386.

tions, the verticalportions of which extensions form between them achamber for the reception of the necessary film roller support, which inthe present instance comprises a pair of duplicate blocks 9 and 10 Fiure 2) disposed in abutting relation to` eac other and removable as aunit from said chamber. Thus the ma azine housing may be constructed ina sing e lunitary structure as by casting. f

nach of tile biockSJe and 1o is bored inwardl from its abutting face forthe reception o a plurality of film guidin rollers, five such rollers11, 12, 13, 14'and 15 ing shown mounted inthe block 9 in Figure 1. Thisarrangement of rollers forms an effective light lock for the film 3during its passage from the supply section 1 to the camera and thence tothe take-up section 2. In order to insure the exclusion of light frombetween the abutting faces of the blocks 9 and 10, each block isprovided in its face with a groove of semicircular form` in crosssection, so that when the vblocks are assembled a tubular opening 16,Figure 2, is. formed between them, said opening extending from side toside of the blocks for the reception of a c lindrical pin. Inasmuch,however, as the b ocks are provided with a pair of slots 17 and 18 forthe passage of the film 3 into and out of the camera, and which slotsintersect the vopening 16 and thus divide the lower portion of theblocks into three separate walls, as clearly indicated in-Figure 1, thepin is necessarily formed in three sections, each of suilicient lengthto extend throughout the thickness of the wall in which it is placed. Itwill thus be seen that it will be impossible for light to penetrateupward between the abutgort the magazine in upright position on a oor orother support when not in use, and assist in centering or guiding themagazine in its operative position on the camera thereby to properlyposition the throat of the magazine with respect to the camera. Thethroat-forming blocks 9, 10 are provided at their lower ends withlateral flan es 21 throu h which they may be removaly secured y means ofscrews 22 to the horizontal walls 8a of the L-shaped extensions of thcmagazine sections, said flangesbeing adapted to lie between theundersides of said walls and the top of the camera. The blocks 9 and 10are further provided on their bottom surfaces with a circular flange 23lying in a plane perpendicular to the flanges 21, the

flange 23 being adapted to extend into snugtting contact with the wallof a circular opening formed in the top of the camera. This arrangementserves not only1 further to insure the proper centering of the magazineon the camera, but by reason of the anguv lar relation of the flanges 21and 23 a lighttight joint is formed between the camera and the magazinehousing. The removability of the blocks 9 and 10 with the film guidingrollers is particularly advantageous in that it permits ready access tothe parts for cleanino, renewing, etc.

Xtending centrally across the undersurface of the two throat-forminblocks 9 and 10, is a strip 24, said strip being secured by screws 25,Figure 2, to that section of the wall of said blocks lying between theslots 17 and' 18 and underlying the central roller 15. The side edges ofthe strip are smoothly rounded off, said strip thus forming a spacer forthe film 3 as it passes into the camera from the supply reel and out ofthe camera to the takefup reel. It will be observed that the lowersurface of the strip 24 lies in a plane above that of the lower surfaceof the legs 19. Because of this arrangement the magazine may be placedin standing position without danger of damaging that portion of a filmthat may be over the strip by contact with the floor or other support."Also, when the magazine is placed in position on the camera, with thebight of the film drawn up against the strip 24, the operator may simplypull the lm downwardly therefrom, within the camera for threading.

The magazine is provided with suitable coverplates or lids for thesupply and takeup sections, each of said cover plates 26 beingpreferably thread-connected with its section as indicated at 27, Fi re2, and provided with a flange 28 over ying said connection thus formingan eective light lock around the top edge of the section. Forfacilitating removal of the cover plates and enabling them to be screwedinto tight engagement with the res ective magazine sections, a pluralityof radially extending ribs 29 may be formed on the outer surfaces of thecove plates. The cover plates and the o positie ends of the magazinesections are pre erably of double-walled construction, and a sound proofpadding 30 interposed between said double walls, as shown in Figure 2.The reel shaft in the take-up section of course extends to the outsideof the magazine housing and is provided with a crossbar 31 or othersuit)- able means for receiving rotary motion in the usual manner. Thechamber in which the throat-forming blocks 9 and 10 are located isprovided with end-closing walls 32 and 33 respectively, see Figure 2,formed integral with the magazine ousing at the opposite ends of saidhousing. For preventing light entering between the sections, each of.the blocks is provided in its top side with a centrally disposedchannel ada ted to engage the lower end of the depen ing wall 6 betweenthe sections, as shown at 34, in Figure 2. Suitable locking meansadapted to be op- Y erated by screws having knurled heads or flanges 35are provided for lockin the magazine to the camera, these devices eingwell known in the art.
